Rankmint is an AI-powered content and SEO toolkit for WordPress site owners who want to improve image accessibility and on-page SEO without juggling several separate plugins.
It bundles tools such as bulk image alt text generation and a full-site SEO audit into one dashboard, aimed at anyone managing a media-heavy site or looking to clean up technical SEO issues without manual, page-by-page work.
The plugin works on a bring-your-own-key basis: you connect your own OpenAI or Google Gemini API key, and Rankmint sends requests directly from your site to whichever provider you select.
For the alt text tool, this means a downscaled copy of each image plus a short instruction is sent to the provider, which returns generated text that appears in your media library for review before it is saved. No content or images pass through any server operated by the plugin’s developer, and usage is billed by the provider you choose.

Key Features of Rankmint
Bulk image alt text generation. Scan the media library to see how many images are missing alt text, then generate accessible, SEO-friendly descriptions for many images at once with a live progress bar that can be canceled at any time. Existing alt text is skipped by default so nothing already written gets overwritten.
Automatic alt text on upload. New images uploaded to the media library can have alt text generated automatically, removing the need to run bulk jobs repeatedly as content grows.
Style and language choices. Alt text can be generated in a chosen style, such as descriptive, SEO-focused, accessibility-first or concise, and in the language you specify, with the option to edit any result before it goes live.
Site-wide SEO health score. The audit tool checks every post and page and produces a single site-wide SEO score, backed by more than a dozen on-page checks covering titles, meta descriptions, headings, content length, readability, image weight, links, indexability and URL slugs.
AI-assisted meta description fixes. Generate a meta description for any page with one click, applying it to Yoast, Rank Math or Rankmint’s own output, or run a bulk fix that writes descriptions for every page currently missing one.
Broken link checker and reporting. Crawl every link on the site to find broken ones along with the pages where they appear, group all detected issues by type, and export the full audit as a CSV file for record keeping.

Good to Know About Rankmint
According to the plugin’s FAQ, Rankmint requires an API key from OpenAI or Google Gemini, since it relies on your own account for AI usage rather than any built-in credits. The developer notes that no images or content are sent to servers it operates; requests travel directly from the site to the chosen AI provider.
Existing alt text is preserved by default through a skip-existing setting, and bulk alt text generation processes images one at a time with a progress bar that can be paused and resumed, which the documentation states makes it suitable for large media libraries.
